Recently I bought a new NDS from my friend and it seemed to be working for few weeks. Now when I charge this thing it doens't charge. So, when I try to turn it on it doesn't even though I had it 'fully charged' an hour ago. I tried to swap the battery with my other ds but didn't work. New ds works when I plug in my charger but when i take it off it doesn't work. I think nds is cursed with some stuff and uses power secreatly. Do I need to buy a new battery or do some advanced thing?
